Check Vehicle Fit

The Monroe® Gas-Magnum® truck shock absorber is designed for mid to full size, hard working pick-up trucks and vans. These units provide firm control without a harsh ride. With up to twice the fluid capacity of standard 1 inch bore shocks, Monroe® Gas-Magnum® truck shocks work more efficiently with less effort.

Product Features:
  • 1-3/8 inch Bore: Lower operating pressure than standard 1 inch bore units
  • 2 inch Reserve Tube: More fluid for more consistent performance.
  • 5/8 inch Piston Rod: Heavy-duty nitrocarburized rod for long service life. On non-dust shield units only
  • All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  • Full Displaced Valving: Better valving range on both the compression and extension cycles of the unit for a smooth comfortable ride.
  • Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
  • Sintered Iron Piston: Stronger than traditional metals, enhances durability for longer service life.
  • Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.
